Fatigue relieving support for steering wheels and the like

ABSTRACT

A system and method for relieving and preventing fatigue caused by extended gripping of a vehicle/vessel steering wheel. The system includes a first section that attaches to the rim of the steering wheel at a predetermined location and a deformable second section that connects to, and extends outwardly from, the first section. The deformable second section supports a portion of the body such as wrists, hands, and forearms.

RELATED APPLICATIONS

This application claims the benefit of priority under 35 U.S.C. §119(e)from U.S. Provisional Application Ser. No. 60/429,130 filed Nov. 26,2002, entitled “Fatigue Relieving Support for Steering Wheels and theLike”, which is incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates to systems and methods that may be used byvehicle and vessel operators to relieve and/or prevent fatigue in thearms and hands when operating directional controls.

BACKGROUND OF THE INVENTION

In learning to drive, a person is taught that the preferable placementof the hands with respect to a steering wheel is at the ten and twoo'clock (i.e., 10:00 and 2:00) positions. These hand locations are saidto give the driver the best control of the operation of the vehicle,which includes automobiles, trucks, tractors, or other types of vehicleswith steering wheels, as well as nautical vessels and aircraft.

If the arms and hands are held on the steering wheel at these locationsfor extended periods of time, they become fatigued. To relieve thisfatigue, often they are removed from the steering wheel and rotated,shaken, or exercised in some way to reenergize them.

In the fatigued state, the arms and hands feel very stiff and lessmobile. Further, in the fatigued condition, the ability of the arms andhands to rapidly react to emergency situations and properly control thevehicle is greatly reduced and accidents are more likely to occur. Thisproblem arises in any vehicle or vessel and is not restricted toautomobiles nor automobile-type steering controls.

There needs to be a system that will prevent and/or relieve thisfatigue, yet not interfere with the operator's ability to control thevehicle or vessel.

SUMMARY OF THE INVENTION

The present invention is a system and method that is associated with asteering wheel or vehicular directional control that relieves orprevents fatigue, for example, when operator drives for extended periodsof time. The system of the present invention may be formed integralwith, or attached to, the wheel or control. Each embodiment of thesystem will provide support to at least a portion of the vehicle orvessel operator's body so as to relieve or prevent fatigue.

The system of the present invention will include at least one part thatextends outward at an angle from a plane across the face of the steeringwheel or vehicular control. This part is at least partially deformablein at least one direction, so that the system will not interfere withthe operation of the wheel or control. This deformability, however, willnot impede the support function of the system on the invention.Furthermore, the deformable material has memory, so that after adeforming force is removed, it resumes its original predeformationconfiguration and shape, which is, extending outward at an angle from aplane across the face of the steering wheel or vehicular control.

It is an object of the present invention to have a system and methodthat may be implemented with the steering control of a vehicle or vesselto prevent or lessen the amount of fatigue that occurs in the arms andhands from driving or steering over extended periods of time.

The features and advantages of the present invention will be morereadily apparent and understood from the following detailed descriptionof the invention, which should be understood in conjunction with theaccompanying drawings and claims that are appended to the end of thedetailed description.

DETAILED DESCRIPTION

For purposes of illustration only, and not to limit the scope of thepresent invention, the invention will be explained with reference to thespecific steering wheel examples indicated in the drawings. One skilledin the art would understand that the present invention is not limited tothe specific examples disclosed and can be more generally applied toother transport means having different steering controls than thosedisclosed.

Referring to FIG. 1, generally at 100, an embodiment of system 101 ofthe present invention is shown attached to steering control 105. System101 includes first section 103 that connects to steering control 105 anddeformable second section 102. First section 103 may be formed from arigid, semi-rigid, or deformable material. If it is deformable, it mayhave memory. Second section 102 that connects to first section 103 maybe formed from a deformable material that has memory.

Deformable material 102 extends outward from the steering control 105over a predetermined section of the steering control which is shown inFIG. 1 to be an arc. Deformable second section 102 may extend outwardlyfrom the steering control at or below the inside circumference of thecontrol over the predetermined arc. This arc will typically include atleast the ten 104 and two 106 o'clock positions, or may include theentire circumference. As shown in FIG. 1, the arc that covers the ten104 and two 106 o'clock positions is disposed on the upper one-half (½)of steering control 105.

Steering control 105 may be a normal steering wheel, with a rim 108 andspokes 110. Alternatively, the steering control 105 may take on otherforms as is known to those in the art, i.e., an aircraft yoke.

In FIG. 2, generally at 200, steering control 211 has two systems of thepresent invention associated with it. The first is shown at 202 and thesecond at 203. The first and second systems in FIG. 2, extend over asmaller arc of the steering control compared to the single system shownin FIG. 1.

The first system of the present invention at 202 includes first section204 that connects to steering control 211 and second section 205 thatextends outward from first section 204. Further, a second section suchas 205 extends outward at an angle from a plane across the face of asteering control such as 211 (see FIG. 3). First section 204 may berigid, semi-rigid, or deformable, while second section 205 isdeformable. If the first section is deformable, it may have memory.

Similarly, the second system of the present invention at 203 includesfirst section 207 that connects to steering control 211 and secondsection 209 that extends outward from first section 207. Further, asecond section such as 209 extends outward at an angle from a planeacross the face of a steering control such as 211 (see FIG. 3). Firstsection 207 may be rigid, semi-rigid, or deformable, while secondsection 209 is deformable. Again, if the first section is deformable, itmay have memory.

In FIG. 2, system 202 is at or near the ten o'clock position and system203 is shown at or near the two o'clock position. As shown in FIG. 2,system 202 that is at or near the ten o'clock position and system 203that is at or near the two o'clock position are disposed on the upperone-half (½) of steering control 211. Although, the two systems havebeen described as being positioned at the ten and two o'clock locations,it is understood that they may be placed at other locations around therim and there may be more than two systems and still be within the scopeof the present invention.

Referring to FIGS. 1 and 2, first section 103 in FIG. 1, and firstsections 204 and 207 in FIG. 2, may be formed integral with steeringcontrol 105 and 211, respectively. Given that the system is disposed ator below the inside circumference of the steering wheel, in thisconfiguration, the operator can securely grip the steering wheel overthe system when the wrists or portions of the hands are resting on thedeformable second section. Further, the first section may be constitutedas an interface to which the second section attaches.

Referring to FIG. 3, generally at 300, steering control 305 is shownthat includes rim 308, spokes 310, and steering column 312. Firstsection 301 is formed integral with rim 308 and deformable secondsection 302 extends outward from the first section. As is shown, secondsection 302 extends outward at angle 316 from plane 318 across the faceof steering control 305. The material of second section 302 hassufficient strength that when driving, the driver may rest his/herwrists or portions of the hands 322 on the material and they will besupported. The structure is such that the weight of the arms and handsthrough the wrists or portions of the hands are supported without thematerial deforming.

When the wrists or portions of the hands are supported, as shown in FIG.3, the driver can firmly grip the steering control rim 308 over firstsection 301 in a manner that he or she has full control of the vehicle.Deformable second section 302 is easily deformable in a directionopposite to which it provides support or any other direction if asufficient deforming force is applied to second section 302. Therefore,if the driver should grip the steering control by pushing the materialupwardly, it will readily deform to permit such a grip. Also, as shownin FIG. 4, generally at 400, if the driver should grip the steeringwheel control rim 308 by grasping it such that deformable second section302 is compressed toward, or below the interior circumference of, thesteering control, it will readily compress and be deformed in such amanner that the driver can grip the steering wheel. Arrows 402 representthe force applied by the driver to the steering wheel control rim 308,resulting in the deformation of second section 302. Second section 302is deformed in this manner so that it will not affect the driver'sability to grasp the steering control in any emergency situation.

Deformable section 302 has memory such that after deforming pressure isremoved, it will return to its original position. When this is done, thesystem of the present invention will appear as shown in FIG. 1, 2, or 3.Once the deformable second section has returned to its originalposition, it will again be in condition to support the arms and handsthrough the wrists or portions of the hands resting on the deformablesecond section.

Referring to FIG. 5, generally at 500, a second embodiment of thepresent invention is shown. System 501 of the present invention shown inFIG. 5 includes a first section 502 that detachably connects to steeringcontrol rim. Deformable second section 503 connects to, and extendsoutwardly from, first section 502. As is shown, deformable secondsection 503 extends outward at angle 516 from plane 518 across the faceof steering control rim 508. First section 502 may snap-on or otherwiseattach to the steering control such that it may appear integral with thesteering control. One of many possible known means for accomplishingthis is by first section 502 being mostly rigid, and leaving a space 507so the attachment can be forced over rim 508 and leave room for thesteering control spokes 510. Regardless of the means for attachment,once first section 502 is attached to the steering control, it willprovide all of the benefits that have been described for the firstsection being integrally formed with the rim. Additionally, the secondembodiment may be a single structure with a single resting materialsupport, a single structure with multiple resting supports, or multiplestructures each with its own resting support.

By way of example, FIG. 6, generally at 600, shows another alternatemethod to attach the system of the present invention to steering controlrim 608. The system in this figure has first section 602 that willenvelop rim 608. First section 602 may be made from a flexible material.First section 602 may have a slit 611, which after this section envelopsthe rim, may be stitched shut by stitches 613. As in the otherembodiments of the present invention, deformable second section 603connects to, and extends outwardly from, first section 602. Further, adeformable second section such as 603 extends outward at an angle from aplane across the face of a steering control rim such as 608 (see FIGS. 3and 5).

It is understood by those skilled in the arts that the system can beadjusted in terms of size and orientation to adapt to different operatorsizes and preferences.
